FUSE CUTTER, SPLITTER, AND CRlMPER SPECIFICATION forming part of hettersI Patent No. 594,852, dated December '7, 1897.

Application filed August 24, 1897.-

To all whom it may concern.-

Be it known that I, CHARLES GUST BRU- NELL, a citizen of the UnitedStates, residing at Custer, in the county of Custer and State of SouthDakota, have invented certain new and useful Improvements inApparatusfor Cutting and Splitting Fuses and Crimping Caps, andPowder-Cutters; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention is an apparatus for cutting and splitting fuses; and itconsists in the novel construction and arrangement of its parts,hereinafter set out in this specification and the claims hereuntoattached.

In the accompanying drawings, Figure 1 is a side view of my invention.Fig. 2 is a top edge view. Fig. 3 is a side view of one of the jaws andone of the handles, the same being in one piece, said View being. partlyin section and partly in perspective. Fig. 4 is a perspective view ofthe cutting-blade. Fig. 5 is a perspective view of the knife-bladespring. 7

My invention is in the nature of a pair of pliers, and consists of twojaws 1 and .2, pivoted together at the point '3. Integral with orsecured to the upper jaw 1- is a'handle 4:, and integral with or securedto the lower jaw is a handle 5., Secured to theinner face and extremeend of the handle 4 is one end of a spring 6, which spring extendsforward and is then bent backand the other end secured to the extremeend and inner face of Th-is,spring is to throw the handles, andconsequently the jaws, open; In the bifurcated front end andupp'er edgeof the jaw 1 is pivoted a knife-blade 7, which knife-blade is providedwith a spring 8, that the blade may be shut down in the slot 9. In thesame slot 9 is secured a blade 10, provided with a cutting edge, theupper part 11 thereof being secured in the same slot 9 by means ofrivets 11,and12. Thecutting part 13 of said blade extends into a slot 14in the lower jaw 2 when the pliers are closed. On the innerface of thelower jaw 2 and running crosswise is a circular notch 15, andrunninglongitudinally with the lower jaw and its en- Serial No. 649,364. .'(Noma.)

tire length is a circular groove-16. Inthe lower face of the upperhandle is a circular notch 17, and on each side of said notch aremortise-holes 18. Inthe upper face of the lower handle is-facircularnotch 19, which 'notch corresponds with notch 17, and on each side ofsaid notch 19 and adaptedto enter the mortise-holes 18 are studs 20. Inthe extreme end of the handle 4 is secured an eye 21, to which isattached a key-chain 22; In the extreme end of the handle 5 isa'depression 23, and in the extreme end of handle 4 is pivoted ahook 24,constructed to catch in the depression 23 and hold the pliers closed.

To use this device, open the blade 7 on the upper side of thejaw 1. Thisblade is for cutting the powder. Close this blade and cut the fuse thedesired length by placing the fuse crosswise in the notch 15 and underthe stationary bladelO. To split the fuse, place the end of the fuselengthwise in the groove 16 in the lower jaw 2 and press the handles.For crimping the cap on the fuse, place the end of the fuse in the cap,placing the cap in circular groove 19 just back of the jaws. Press thehandles, and the cap is pressed tightly to the fuse. r

This invention is for use in the mines where powder, caps, and fuse areused and for all places where rock is blasted.

I-Iavin g described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination of a bifurcated jaw 1,having the handle 4, provided with circular notch 10 and studs 20;notched, grooved and slotted jaw 2, having the handle 5, pivoted to jaw1 and provided with circular notch 17, and mortise-holes18; blade 10,secured in the bifurcated jaw 1, its cutting edge 13, adapted to enterthe slot 14, in thejaw 2, substantially as shown and describedandfor thepurposes set forth.

2. Thecombination of the bifurcated jaw 1, having the handle 4, providedwith a circular notch'19 and studs 20; notched, grooved and slotted jaw2, having the handle 5, pivoted to the jaw l, and having circular notch17 and mortise-holes 18; knife-blade 7, pivoted in the bifurcated jaw 1;blade 10, secured in the same bifurcated jaw, 1, its cutting edge 13,

adapted to enter the slot 14, in the jaw 2, substantially as shown anddescribed and for the purposes set forth.

3. The combination of the bifurcated jaw 1,

' same bifurcated jaw, 1, its cutting edge 13,

adapted to enter the slot 14, in the jaw 2; spring 6, having its extremeends secured to the extreme ends and inner faces of the han dles 4, 5,substantially as shown and described and for the purposes set forth.

4. The combination of the bifurcated jaw 1, having the handle 4,provided with a circular notch 19 and studs 20 notched, grooved andslotted jaw 2, having the handle 5, pivoted to the jaw 1, and havingcircular notch 17, and mortise-holes 18; knife-blade 7, pivoted in thebifurcated jaw 1; blade 10, secured in the same bifurcated jaw, 1, itscutting edge 13, adapted to enter, the slot 14, in the jaw 2; spring 6,having its extreme ends secured to the extreme ends and inner faces ofthe handles 4, 5; eye 21, adapted to carry a key-chain.

22, substantially as shown and described and for the purposes set forth.

5. Thecombination of the bifurcated jaw 1, having the integral handle 4,provided with a circular notch 19 and studs 20; notched, grooved andslotted jaw 2, having the integral handle 5, pivoted to the jaw 1, andhaving circular notch 17, and mortise-holes 1S; knife-blade 7 pivoted inthe bifurcated jaw 1; blade 10, secured in the same bifurcated jaw, 1,its cutting edge 13, adapted to enter the slot 14, in the jaw 2; spring6, having its,

extreme ends secured to the extreme ends and inner faces of the handles4, 5; hook 24, pivoted in the extreme end of handle 4, and adapted tocatch in the depression 23, of handle 5, substantially as shown anddescribed
